cobertura maven插件是否不'；在接口中不能使用java8默认方法声明？

我已经用java8 defult方法声明了我的接口：

public interface MyInterface {

    default String myMethod(String str) {
        //IMPLEMENTATION
    }
}

    "}" ...
    ";" ...

接下来，我执行了maven目标：

mvn cobertura:cobertura

日志显示错误，因为cobertura不支持java8默认方法声明：

public interface MyInterface {

    default String myMethod(String str) {
        //IMPLEMENTATION
    }
}

[INFO]我已更改为JaCoCo maven配置，它工作正常

显然，对Java 8没有（真正的）支持。CHANGELOG声称支持2.1.1，但是有很多未解决的问题和线程报告问题…我建议使用JaCoCo而不是cobertura，因为自从Java 6以来不再需要插装…好的，khmarbaise，我将尝试JaCoCo！
